Hi everyone,
The problem arises when two or more Universes are working together, then
if the ColoringAttributes from one shape is changed (under some
circumstances) the following message is showed:
---------------------------------------------------------------------------------------------------------------

This code reproduces the bug pressing two times the "Change Color"
Button: (only tested for W98 and Java3D 1.2 Beta1).
kind regards
